why aren't there any rankings in nmat mocks to compare my score with others. this is the basic requirement from any test series.

Hi
NMAT is an adaptive mock and the scoring is similar to that you will get in the actual exam. In NMAT your score is mainly determined by the level of questions attempted and accuracy and it is possible to score more marks than someone even if you both attempted same number of questions but you attempted more number of tough questions correctly . So I would advice you to keep a check on your scores for NMAT mocks .
